Chapter 1 – Introduction and Product Description

Safety Warnings

General Safety

The modem is designed and intended to be used in either fixed or mobile applications. In the “Fixed” application, the
device is physically secured at one location and not easily moved to another location. In the “Mobile” application, the
device may be regularly moved to different locations.

Caution! Maintain a separation distance of at least 20 cm (8 inches) between the transmitter’s antenna and the body

of the user or nearby persons. The modem is not designed for, nor intended to be, used in applications within 20 cm
(8 inches) of the body of the user. Such uses are strictly prohibited.

• Avoid possible radio frequency (RF) interference by carefully following the safety guidelines below.

• Switch OFF the MultiModem in the vicinity of gasoline or diesel-fuel pumps or before filling a vehicle with fuel.

• Switch OFF the MultiModem in hospitals and any other place where medical equipment may be in use.

• Respect restrictions on the use of radio equipment in fuel depots, chemical plants, or where blasting

operations are in progress.

• There may be a hazard associated with the operation of your MultiModem in the vicinity of inadequately

protected personal medical devices such as hearing aids and pacemakers. Consult the manufacturers of the
medical device to determine if it is adequately protected.

• Operation of the MultiModem in the vicinity of other electronic equipment may cause interference if the

equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Vehicle Safety

• Do not use your MultiModem while driving.

• Respect national regulations on the use of cellular telephones in vehicles. Road safety always comes first.

• If incorrectly installed in a vehicle, the operation of MultiModem telephone could interfere with the correct

functioning of vehicle electronics. To avoid such problems, be sure that the installation has been performed by
qualified personnel. Verification of the protection of vehicle electronics should be part of the installation.

• The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.

Maintenance of the Wireless MultiModem

Your wireless MultiModem is the product of advanced engineering, design, and craftsmanship and should be treated
with care. The suggestions below will help you to enjoy this product for many years.

• Do not expose the MultiModem to any extreme environment where the temperature or humidity is high.

• Do not attempt to disassemble the MultiModem. There are no user serviceable parts inside.

• Do not expose the MultiModem to water, rain, or spilled beverages. It is not waterproof.

• Do not abuse your MultiModem by dropping, knocking, or violently shaking it. Rough handling can damage it.

• Do not place the MultiModem alongside computer discs, credit or travel cards, or other magnetic media. The

information contained on discs or cards may be affected by the phone.

• The use of accessories not authorized by Multi-Tech or not compliant with Multi-Tech’s accessory

specifications may invalidate the warranty of the MultiModem.

• In the unlikely event of a fault in the MultiModem, contact Multi-Tech Technical Support.

Handling Precautions

All devices must be handled with certain precautions to avoid damage due to the accumulation of static charge.
Although input protection circuitry has been incorporated into the devices to minimize the effect of this static build up,
proper precautions should be taken to avoid exposure to electrostatic discharge during handling and mounting.

Safety Recommendations for Rack Installations

• Ensure proper installation in a closed or multi-unit enclosure by following the recommended installation as

defined by the enclosure manufacturer.

• If installing the wireless modem in a closed or multi-unit enclosure, ensure adequate airflow so that the

maximum recommended ambient temperature is not exceeded.

• Do not place the device directly on top of other equipment or place other equipment on top of this device.

• Ensure that the device is properly connected to earth ground via a grounded power cord. If a power strip is

used, ensure that the power strip also provides adequate grounding.

• Ensure that the main supply circuit is capable of handling the load. See the power label on the device for

requirements.

• Maximum ambient temperature is 70 degrees Celsius.

• This device should be installed by properly qualified personnel.

• Only connect like circuits; e.g., connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN

(Telecommunications Network) circuits to TN circuits.
